Lots of reasons:
Depending on the specific STD, the first person tested might have a false positive, or the second a false negative result. Maybe partner not infected yet, if other partners involved. Most STDs are cured over time by the immune system, so the partner might have self cured. Or took an antibiotic, either for the STD or something else. Both partners should be treated, including the one with neg test.

This is a disease which can be transmitted from one person to another person through sexually related activities. This does not limit these activities to heterosexual intercourse, but encompasses all modalities of human-to-human sexual activity. It does not include illnesses that may make an individual more susceptible to a condition because of a sexual activity (e.g., bacterial vaginitis).

Call and ask them!:
Most clinics -- whether Planned Parenthood or public health STD clinics -- expect patients to telephone for their test results. Some may send results by text or email if requested. The clinic may try to contact you if a test is positive, but not for negative results. It varies widely -- one PP clinic may do it different than the next. If you have been tested and aren't sure, call them!

Yes for some STDs:
Some antibiotics are active against chlamydia, gonorrhea, and syphilis and could cure the infection, making the test negative. Even worse, it might suppress the infection so the test is negative, but not cure it. However, antibiotics have no effect on viral STDs like herpes, HPV, and viral hepatitis. On the other hand, if you are at risk, don't delay testing because of this.

Offices are busy:
And they have lots of patients to contact. They are not going to leave sensitive information like that (good or bad) on an answering machine. Most offices call back with both positive results and negative results. Call them back and somebody should be able to give you the message they were trying to give you.

No problem:
This will make no difference at all. The urine STD tests detect infection because they rinse the urethra (urine passage). No matter now dilute the urine, it will flush any gonorrhea or chlamydiabacteria into the specimen and testing will be accurate.

No.:
How will you be testing for these agents? Some require culture, some depend on antibody production, some use DNA technology. Tests dependent on antibody production are not likely to turn positive in two weeks. It would be preferable to see your doctor for the correct choice of tests.

NGU is STD, UTI isn't:
Urinary tract infection (UTI) and nongonococcal urethritis (NGU) are separate problems. But some doctors don't know the difference and diagnose UTI in men with NGU. UTIs are rare in men under age 35. Most NGU has negative STD tests, but it's still an STD.

Couple of ideas:
This could be ngu, or "non-gonoccocal urethritis" - an infection not related to an std. You should see your doctor and have a culture of the discharge taken, as well as a urinalysis and repeat std testing.

Accuracy depends:
There are several different tests for chlamydia and culture is the most reliable as far as positives go since you can't grow what isn't there but it is not all that reliable if negative since sometime things that a there fail to grow. Think of your garden. However, cultures are seldom done any more. Testing is almost always based on DNA now and is very reliable.
